A hydraulic mount provides active control of dip rate performance through use of an orifice track connecting a primary pumping chamber of the mount to a secondary fluid chamber having a movable wall, and an actuator for regulating pressure applied to the movable wall for controlling movement of the movable wall. With little or no pressure applied to the movable wall, the mount provides significant isolation and very little damping in a predetermined and designed frequency range. As pressure is applied to the movable wall, the stiffness of the mount is increased significantly, to thereby provide substantial damping.
